Abstract: A leakproof makeup applicator includes a main body, a rod, a collar and a bottle. The main body defines a receiving space therein. A power supply, a motor and a connector are disposed in the receiving space. The power supply electrically connects to the motor, and the connector is driven by the motor to be rotatable with respect to the main body. The rod connects to the connector concentrically and has a sealing sleeve disposed thereon. The bottle defines a liquid chamber and an opening formed at one end thereof. The opening has a plastic ring disposed on its inner periphery, in which the plastic ring defines a through hole. The rod inserts into the liquid chamber via the through hole. The sealing sleeve seals the through hole as the bottle and the collar are threadedly combined with each other.

Abstract: A mascara applicator includes a main body, a rod and a bottle. The main body defines a receiving space therein. The main body has a power source and a reversible DC motor. The power source electrically connects to the DC motor. The DC motor includes a rotor. At least one counterweight block is disposed on the rotor so that a center of mass of the rotor is offset from the axle. The rod has a first end attached to the axle in a rotational operative relationship and a second end attached with an applicator head. The bottle defines a liquid chamber and an opening. The opening communicates with the liquid chamber, and the rod extending into the liquid chamber through the opening. The rod is sleeved with a gasket, so that the gasket blocks the opening and seals the liquid chamber when the main body is affixed to the bottle.

Abstract: A fastening mechanism for an electronic device for connecting upper and lower casings of an electronic device, includes: a side frame member including an exposed surface, a first surface and an opposing second surface; a wedging portion formed on the first surface, for being coupled with a protruding edge formed on the upper casing; a stopping portion formed on the second surface, for abutting against an edge of the lower casing; and at least one locking portion formed on the side frame member, and extended toward a direction opposed to the exposed surface so as to further fasten the upper casing, the side frame member and the lower casing by means of a locking element, making the upper casing, the exposed surface of the side frame member and the lower casing form a case of the electronic device.

Abstract: A hard drive connecting device for a notebook PC is installed in a case of the notebook PC for connecting a main board and a hard drive in the case, which includes a flexible board having at least a first side, at least a second side, and conductive lines for electrically connecting the first side to the second side; a first connector located in the hard drive bay electrically connected to the first side for electrically connecting the hard drive; and a second connector electrically connected to the second side for electrically connecting the main board. The flexible board facilitates electrical connection of the hard drive that allows reduction of both the size of the hard drive and the installation space required for the hard drive, thus facilitating profile miniaturization of notebook PCs.

Abstract: A key structure applicable in an electronic device for pressing an electrical button of the electronic device is disclosed. The key structure includes an annulus section for fixing the key structure in the electronic device, and a pair of key sections, each of which extends from the annulus section and has a protruding section and a retention section, wherein the protruding section protrudes out of an inner wall of the key section to prevent the key section from sinking, and the retention section extends from at least one side of the key section to prevent the key section from protruding upwards. With each key section being additionally provided with the protruding section and the retention section, the key structure efficiently prevents the key sections from protruding upwards and sinking.
